MACHINE TOOLS, METAL CUTTING TYPES

This industry details establishments primarily engaged in manufacturing metal cutting type machine tools, not supported in the hands of an operator when in use, that shape metal by cutting or use of electrical techniques; the rebuilding of such machine tools; and the manufacture of replacement parts for them. Also included in this industry are metalworking machine tools designed primarily for home workshops. Establishments primarily engaged in the manufacture of electrical and gas welding and soldering equipment are classified in SIC 3548: Electric and Gas Welding and Soldering Equipment ; those establishments manufacturing portable power-driven handtools are classified in SIC 3546: Power-Driven Handtools.

Industry Snapshot

The metal cutting industry is concerned with the removal of metal from a larger piece of metal to create a desired shape. Metal cutting, also referred to as machining, is performed on most manufactured items. The uses range from low-precision machining, such as grinding undesired protrusions from a rough casting, to high-precision machining, which involves working tolerances of less than half the thickness of a human hair (0.0001 inch). Classic metal cutting produces scrap pieces, called chips, that are relatively useless and generally cannot be reused through remelting or pressing. Both the environmental and economic consequences of such waste have created new processes referred to as chipless machining. General machining processes include turning, shaping, milling, drilling, sawing, abrasive machining, and broaching.

The machine tool industry as a whole is closely tied to national and world economic conditions. The total shipments of metal cutting machine tools dropped sharply between 1982 to 1983 from $4.5 billion to below $3 billion. From that point, shipments recovered somewhat, but remained greatly reduced. The worldwide recession of the late 1980s and early 1990s created a trough in machine tool-related sales. Shipments between 1990 and 1994 varied only slightly, hovering around $3.5 billion. By the late 1990s shipments had recovered, climbing to $5.33 billion in 1997; however, levels began to decline again in 1998, a trend which continued into 2000, when shipments totaled $4.48 billion. In the late 1990s, 369 establishments participated in this industry.
